South Devon Railway sea wall

The South Devon Railway sea wall is situated on the south coast of Devon in England. It is probably the most photographed section of railway in the United Kingdom as a footpath runs alongside the railway between Dawlish Warren and Dawlish, and another footpath forms a continuation to the sea front promenade at Teignmouth. Both these form part of the South West Coast Path.

The South Devon Railway was built to the designs of Isambard Kingdom Brunel and takes a route from Exeter which follows the River Exe to Dawlish Warren, runs beneath the sea cliffs to Teignmouth, and then follows the River Teign to Newton Abbot. It follows tidal waters for about 13 miles, 4 of which are open sea.


The section was opened by the South Devon Railway Company, running from Exeter St Davids railway station to Teignmouth railway station on 30 May 1846 and extended to Newton Abbot railway station on 31 December 1846. It was a broad gauge railway of 7 feet ¼ inch gauge and intended to be worked as an atmospheric railway, although atmospheric trains only ran from 13 September 1847 until 9 September 1848.

The South Devon Railway was amalgamated into the Great Western Railway on 1 February 1876 and the gauge converted to the standard 4 feet 8½ inches after 20 May 1892. A station was opened to serve Dawlish Warren in 1905, all the other stations on the Sea Wall having opened with the line in 1846.

The Great Western Railway was nationalised into British Railways on 1 January 1948. The line is now owned by Network Rail and the stations and majority of trains operated by First Great Western.

The route
River Exe

The river comes into view at Turf. The square pond and disturbed ground between the railway and river are the remains of Turf engine house, one of the engine houses used for powering the atmospheric trains. After a short distance the river wall comes alongside the railway at Powderham. After passing the railway then runs between the river and the deer park of Powderham Castle, to Starcross railway station, situated in the middle of Starcross village. Opposite the pier for the ferry to Exmouth is the Starcross engine house.

A little further along the river, the railway crosses the mouth of Cockwood harbour. Near here was the 1,285 feet long Exe Bight Pier, in use from 1869 for about ten years. On the opposite side of the river trains can sometimes be seen near Lympstone Commando railway station.

The river enters the sea at Exmouth while the railway runs behind the sand dunes of Dawlish Warren to reach Dawlish Warren railway station.

Sea Wall

On leaving Dawlish Warren the railway comes onto the Sea Wall proper with the walkway alongside, although it quickly enters the short and deep cutting at Langstone Rock. Emerging above the beach, views can be had towards Torbay.

The footpath is level with the railway except for a short section at Sea Lawn where it drops down almost to beach level. this section is impassable on foot at high tide and so walkers need to cross the line on Rockstone Footbridge and return to the sea wall using another footbridge at Coastguard's Cottage. Now a cafe, this building was used by the railway during its construction and then sold to the coastguard. Their boat house is below the footbridge.

Immediately beyond the Coastguard Footbridge are the long platforms of Dawlish railway station with the town seen off to the right from Colonnade Viaduct at the other end of the station.

The line now enters its first tunnel, Kennaway, beneath Lea Mount, beyond which is Coryton beach, the furthest point accessible by the sea wall footpath from Dawlish. The Coryton tunnel leads to the next beach, Shell Cove, accessible by foot only via the shore at very low tide or by a private path from the clifftop. The railway then passes through Phillot Tunnel and Clerk's Tunnel, emerging onto a section of sea wall at Breeches Rock before diving into Parson's Tunnel beneath Hole Head. The last two tunnels are named after the Parson and Clerk Rocks, two stacks in the sea off Hole Head.

Beyond Parson's Tunnel is a short viaduct across Smugglers Lane and then the footpath resumes for the final stretch past Sprey Point to the cutting at Teignmouth Eastcliff. On the landward side of the railway near Sprey Point can be seen the remains of a lime kiln used during the construction of the line.

River Teign

After passing through Teignmouth railway station the line continues through a cutting to emerge behind the busy Teignmouth Harbour, after which the railway resumes its course alongside the water, the River Teign. The cuttings on both sides of the station were originally tunnels and were opened out between 1879 and 1884.

After going under the Shaldon Bridge and passing a boat yard on the site of Teignmouth gas works, the line follows the river past the small promontories at Flow Point, Red Rock, and Summer House, before passing though two small cuttings and crossing Hackney Marshes near the race course to reach Newton Abbot railway station.

Across the river opposite Summer House can be seen the waterside inn at Coombe Cellars.

Maintenance and the future

Running parallel to the open sea at the base of cliffs for four miles, the sea wall has always been prone to damage during rough weather. In December 1852 a large landslip from the cliffs east of Teignmouth caused the railway to close for four days, and in 1855 and 1859 the sea broke through the line at Teignmouth. There have been many more closures since, caused both by landslips from the cliffs and breaches by the sea, especially in winter. In 2010 it was stated in Parliament that "in recent years" around £9 million had been invested on keeping the sea wall safe and the cliff faces stable, and that the ongoing maintenance of the sea walls and the adjoining estuaries was costing Network Rail around £500,000 annually.

In 1936 the Great Western Railway surveyed an inland deviation between Exminster and Bishopsteignton and a shorter route starting near Dawlish Warren, but the advent of World War 2 brought these projects to an end. In a Parliamentary debate in 2010, the Under-Secretary of State for Transport reiterated the importance of the line to the economy of South Devon and Cornwall, and confirmed that even if there were to be plans for the building of an alternative inland route in the future, "in our view, it would not be a substitute in any shape or form for the main line along the coast". This is despite the acknowledgement of an inevitable increase in maintenance costs due to rising sea levels.
